Merci Bonne extension

Excellent addition! Unfortunately there are not enough websites on which all 4 squares green :)

I've been looking for a replacement for CZ.NIX Labs' DNSSEC/TLSA Validator, which I still use in Cyberfox.

For Firefox Quantum, I found Popineau's DNSSEC unsatisfactory at least until the promised DNS over HTTPS (DoH) service is fulfilled at which point I'll re-evaluate. But it's been three months since their last update...

So, upon an icon click, HTTPS+ Checker queries a server (port 443) in France and presents a color coded result to the four fields.

As such, and given its experimental nature, the ability, validity and security of this extension must rest upon the user's confidence in AMZG_Beu's expertise, methodology and strategy. And, of course, that of Mozilla's vetting.

At this point I can't find reason to doubt that confidence and give five stars for effort, implementation and apparent efficacy.

I look forward to continued development and success. Good luck and thank you.
